Email Rules

Email covers a broad category of services. Some errors are easy to diagnose while others require a bit of investigation. This article is intended to help with that investigation. Skim through the topics in this section to see if your specific issue is addressed. Here are the most common problems with email and suggest ways to fix particular issues.

 

 

Bouncebacks

If you attempted to send an email message to a third-party mail server and received a bounceback – please, check the following:

1. Read the bounceback message. Usually it contains the reason why the email was bounced back to you. Some common reasons are:

  • Poor reputation. This means your mail server is on the recipient’s block list.
  • Recipient does not exist. This means the target email address is no longer valid.

2. If the bounceback seems difficult to interpret – go ahead and contact our support team, they’ll help you troubleshoot any complicated issues.

3. Certain servers require DomainKeys (DKIM) and/or an SPF record configured on your side.

Cannot receive emails

There exists a decent number of reasons that may cause you not to be able to read emails. The most common are:

1. Username is incorrent. Most email clients only suggest the first part of the email address (user instead of user@domain.com) as the username, while our email servers require the full email address to be used as the username.

2. Using SSL on non-SSL ports. If you want to use SSL for your incoming emails – make sure you are using one of the following ports:

  • POP3 (SSL): 995
  • IMAP (SSL): 993

3. Wrong ports (non-SSL). If you are not using SSL – make sure you are using one of the following ports:

  • POP3: 110
  • IMAP: 143

4. Wrong host/server. Make sure you are using the correct server for incoming emails. In most cases you can use mail.domain.com (where domain.com is your domain name).

Can’t Send Emails

1. SMTP Authentication. Our email servers require SMTP authentication for any emails to be sent. This can be enabled in the advanced settings section of your email client.

2. SMTP username is incorrent. Most email clients only suggest the first part of the email address (user instead of user@domain.com) as the username, while our email servers require the full email address to be used as SMTP username.

3. Using SSL on non-SSL ports. If you wish to use SSL for your outgoing emails – make sure you are using port 465 for SMTP (SSL)

4. Wrong ports (non-SSL). If you are not using SSL – make sure you are using the following ports:

  • SMTP: 25
  • Alternate SMTP: 26

5. Wrong host/server. Make sure you are using the correct SMTP server for outgoing emails. In most cases you can use mail.domain.com (where domain.com would be your domain name).
